Graham Audio LS5/9f Floorstanding Monitor Loudspeakers

Graham LS5/9F Loudspeakers Provide Floor-Standing Heritage Sound

Graham LS5/9F is a floor-standing loudspeaker designed as a faithful yet enhanced evolution of the legendary BBC LS5/9 monitor. This model delivers the same meticulous tonal accuracy and natural sound reproduction, now adapted for listeners seeking a full-height cabinet with broader dynamic performance and extended bass articulation.

Graham LS5/9F Offers Studio-Grade Heritage in a Full-Sized Format

Graham LS5/9F loudspeakers are a 2-way, reflex-loaded system built around the iconic BBC specification. At the heart of each speaker is a hand-crafted 200mm Diaphanone polypropylene bass/midrange unit from Volt, paired with the precision-matched 34mm Son Audax HD13D34H tweeter. These transducers, selected to tight tolerances, provide exceptional midband clarity, natural vocal presentation, and refined treble accuracy.

The floor-standing cabinet design delivers improved low-frequency extension over the original LS5/9, producing deeper, more authoritative bass. With a frequency response from 40Hz to 16kHz (±3dB) and sensitivity rated at 87dB SPL (2.83V, 1m), the LS5/9F is both musically expressive and room-filling.

Cabinet Design Enables Greater Dynamics and Acoustic Presence

The enclosure of the LS5/9F features a thin-wall construction in line with traditional BBC design methodology, using real wood veneer finishes for acoustic transparency and visual refinement. The expanded internal volume boosts the speaker’s low-end performance while preserving the tonal neutrality that made the original LS5/9 an industry benchmark.

Each speaker weighs 25kg, delivering a reassuring sense of physical and acoustic presence. Its structure supports improved bass control and mechanical stability, contributing to dynamic impact and tonal coherence.

Tweeter Level Switching Enables Flexible Room Matching

Graham LS5/9F includes a discrete HF level switch, inspired by user-driven development. This toggle, first implemented in the LS6 series, replaces the soldered resistor network used in earlier versions. It allows subtle adjustment of high-frequency output to better suit challenging acoustic spaces, such as heavily upholstered rooms or those with absorbent finishes. The feature offers useful calibration flexibility without compromising tonal accuracy.

Designed for Moderate to High-Power Amplifiers

With an impedance of 8 ohms and a recommended amplifier power range of 50 to 200 watts (unclipped programme), the Graham LS5/9F partners effortlessly with a wide range of high-quality solid-state and valve amplification. The speaker is capable of producing over 100dB SPL (pair at 2m), offering ample headroom for both domestic and professional use.

Graham LS5/9F Combines Classic Engineering with Contemporary Utility

This model stands apart in the Graham Audio range as a rare example of a BBC-inspired floor-standing loudspeaker, merging classic design heritage with practical modern refinements. Teak and sprayed finishes are available by special request, enabling personalisation to complement a range of interior aesthetics.

With its high-fidelity pedigree and extended bass capability, the Graham LS5/9F floor-standing loudspeaker appeals to discerning listeners who demand studio-accurate sound reproduction in a more dynamic, full-range format.
